I use Internet Explorer and often have a number of windows left open, each with a number of tabs open in them (to simultaneoulsy use the internet for work, school and personal tasks). However, this inevitably bogs down my computer. I can't really limit my tabs/windows without having to start from scratch on every project though, and really do need to keep them open for days at a time while I continually work on everything.
Is there something I can do to help my machine not get bogged down? More tabs in a single window or more windows without tabs, or a different browser or ad-on? Or just deal with starting over every time I sit down or change tasks?
